TRS-80 Model Model I Information Links


In the early 1970s, most personal computers came as hobbyist kits requiring a high level of technical expertise to assemble. Don French, a buyer for the consumer electronics chain Tandy Radio Shack (TRS), believed that Radio Shack should offer an assembled personal computer and hired engineer Steve Leininger to design it. In the summer of 1977, Radio Shack introduced the TRS-80 for $599. This offering included a BASIC language interpreter, four kilobytes of RAM, a Zilog Z80 processor at 1.77 megahertz, a twelve-inch video monitor, a cassette recorder, a power supply, and a cassette tape containing the games Blackjack and Backgammon.
